Uses
Benzyl Alcohol (CAS NO.100-51-6) is used as a bacteriostatic preservative at low concentration in intravenous medications. It is also used as a general solvent for inks, paints, lacquers, and epoxy resin coatings.In organic synthesis, benzyl esters are good protecting groups due to they can be removed by mild hydrogenolysis. Besides Benzyl alcohol has been used as a dielectric solvent for the dielectrophoretic reconfiguration of nanowires. Moreover it is also a precursor to a variety of esters, used in the soap, perfume, and flavor industries. It is often added to intravenous medication solutions as a preservative because of its bacteriostatic and antipruritic properties. At last it is also used as a photographic developer.
Production
Benzyl alcohol is manufactured by hydrolysis of benzyl chloride.
C6H5CH2Cl → C6H5CH2OH
